采用丙烯酰胺(AM)、丙烯酸(AA)以及单六位取代烯丙胺基β-环糊精(NCD)为原料,合成出了一种水溶性聚合物 AM/ AA/ NCD。采用喹啉、溴乙烷、氟硼酸钠在温和条件下合成了离子液体四氟硼酸1-乙基-喹啉盐([equin]BF4)。AM/ AA/ NCD 溶液与[ equin]BF4在50℃下回流,发生复合反应,生成 AM/ AA/ NCD-离子液[equin]BF4复合粘土稳定剂。考察了反应条件对聚合反应的影响,确立了最佳合成工艺。通过膨润土线性膨胀实验,确定了复合粘土稳定剂最佳加量为0.6%,防膨率达到81%。采用 X-射线衍射(XRD)考察了复合粘土稳定剂对钠蒙脱土晶层间距的抑制效果,晶层间距从1.89 nm 降低到1.66 nm。压入硬度实验表明,AM/ AA/ NCD-[equin]BF4能有效保持泥页岩岩石强度。

A novel copolymer AM/ AA/ NCD was prepared by acrylamide(AM),acrylic acid(AA)and mono-6-(allyl amino)-β-cyclodextrin(NCD). Ionic liquid[equin]BF4 was synthesized using quinolin, bromoethane and sodium fluoroborate(NaBF4 )as starting materials. AM/ AA/ NCD Solution and[equin] BF4 were mixed and refluxed at 50 ℃ for incorporation reaction yielding AM/ AA/ NCD-[ equin]BF4 as clay stabilizer. The structures of AM/ AA/ NCD and[ equin]BF4 were confirmed by Infrared( IR) spectroscopy. The anti-swelling ratio could be 81% when the concentration of clay stabilizer was 0. 6% . The result of X-ray diffractometry(XRD)test showed that the solutions of obtained copolymers could re-markably reduce the interlayer spacing of sodium montmorillonite(from 1. 89 nm to 1. 66 nm)and im-prove the indentation hardness of shale.
